<p style="text-align:center"><strong>Jan. 23-25, 2019, K&ouml;nigstein </strong></p>
<p style="text-align:center"><strong>Accelerator Operations </strong></p>
<p style="text-align:justify">The long expected beam time 2018 was started as planned in June, 2018. Nevertheless, the execution of the beam time 2018 has been quite rocky. A few major technical issues such as the high intensity RFQ as well as the commissioning of the FAIR controls have posted limitations on re-establishing the expected operation capabilities such as high intensity heavy ion beams, parallel operations, etc. The unexpected arc of the UNILAC single gap resonators ER1 due to the imperfection of the newly renovated LINAC RF gallery ventilation system forced extended downtime in order to execute though cleaning of the affected areas and equipment. As the result, the planned operation for Physics data taking of beam time 2018 and 2019 has to be shifted to the beginning of 2019 and 2020 respectively.</p>
<p style="text-align:justify">Despite all the unexpected difficulties and hiccups, a lot of progresses have been made in a number of areas such as commissioning SIS18 with the new FAIR control system., electron cooling recommissioning, ESR commissioning as a synchrotron with the new controls, 2.7 Hz uranium source development, etc.</p>
<p style="text-align:justify">To summarize what have been achieved and what need to be further improved to ensure the success of FAIR phase 0, we would like to call the second GSI/FAIR beam time retreat in late January 2019 to focus on the following topics</p>
<p style="text-align:justify">&bull; what have been achieved of the beam commissioning?</p>
<ul>
<li style="text-align:justify">systems: UNILAC LEBT QQ, FAIR controls, beam instrumentation, beam cooling etc</li>
<li style="text-align:justify">accelerators: SIS18, ESR, CRYRING</li>
</ul>
<p style="text-align:justify">&bull; performance review</p>
<ul>
<li style="text-align:justify">from the operations point of view, including what have been achieved during the 2018 engineering run</li>
<li style="text-align:justify">from experimental point of view</li>
</ul>
<p style="text-align:justify">&bull; dedicated lesson-learn session to go over the major incidents and limitations, and brainstorm how to avoid these in the future</p>
<p style="text-align:justify">&bull; what beam performance can be expected for Physics run in 2019 and 2020? And, what are the requirements and expectations from the approved experiments?</p>
<p style="text-align:justify">Similar to our first beam time retreat, two guests from international accelerator complex based user facilities will also be joining us to share with us their experiences in operation as well as accelerator improvements.</p>
<p style="text-align:justify">Please find the logistic information regarding the retreat just here. Should you need more information, please contact us (p.lindenberg@gsi.de and j.stein@gsi.de).</p>
<p style="text-align:justify">We look forward to a fruitful discussion with you and other colleagues.</p>
